Neutral tooth (N)
The Neutral tooth has a cutting angle of 0°. It is suitable for cutting material with an high carbon content (such as cast iron), for material with small cross sections and for thin-wall profiles and tubes.
P Tooth (P)
The P tooth has an extremely aggressive cutting angle. Due to its extremely aggressive cutting characteristics is most suitable for cutting high alloyed materials, exotic alloys and non-ferrous metals.
Ground tooth (R)
The R tooth is based on a high-low triple chip design recognized as one of the most efficient in engineering cutting technology. To cope with the demands of a wide range of difficult steels and exotic alloys the teeth are available with poisitve and extremely positive cutting angles.
